Knee Ankle Foot Orthosis

The Active plus-Knee comes furnished with a pneumatic spring on the lateral side of the joint to assist with knee extension during the swing phase of gait.

A medial knee joint is also included to help control knee alignment and give Medio lateral stability.

The active plus -Knee is a free motion knee joint that is designed to provide extension assist, not prevent knee flexion. Available with your choice of a 75N, 125N (for standard applications), or 175N pneumatic spring.

The term KAFO is an acronym that stands for Knee-Ankle-Foot Orthosis and describes the part of the body that this device encompasses. This device extends from the thigh to the foot and is generally used to control instabilities in the lower limb by maintaining alignment and controlling motion. Instabilities can be either due to skeletal problems: broken bones, arthritic joints, bowleg, knock-knee, knee hyperextension or muscular weakness and paralysis. With this in mind, the indications for the use of a KAFO are many and varied and any one particular design is specific to the needs of the person it is made for.

A KAFO is a device that is used to control instabilities in the knee and lower limb by maintaining proper alignment and controlling motion. Instabilities can be caused by broken bones, arthritic joints, hyperextension of the knee, muscle weakness and/or paralysis. As there are many different reasons that a person may need to utilize a KAFO, there are many different designs for a KAFO based on necessity.

It is made up of Indian Made drop Lock knee Joint. We manufacture the Orhtosis by POP casting, that’s why it give proper fitment.

A knee-ankle-foot orthosis (KAFO) consists of a plastic AFO or an AFO with metal uprights, a mechanical knee joint, and a plastic thigh cuff or 2 metal thigh bands. KAFO's can be used in quadriceps paralysis or weakness to maintain knee stability and control flexible genu valgum or varum.

KAFO's are also used to limit the weight bearing of the thigh, leg, and foot with quadrilateral or ischial containment brim. A KAFO is more difficult to don and doff than an AFO, so it is not recommended for patients who have moderate-to-severe cognitive dysfunction.

The most common causes of muscle weakness include :

• Poliomyelitis
• Muscular Dystrophy
• Multiple Sclerosis
• Spinal cord injury

The Neurotronic knee joint system is a sophisticated electro mechanical knee control component designed specifically for people with knee extensor weakness, knee instability or loss of knee control and sets the benchmark for this class of limb control technology.

The Neurotronic is incorporated into a discreet lightweight carbon frame, locking automatically in stance phase and free moving in swing phase. In stance phase, the Neurotronic stabilises the knee in any position to enable the user to safely load the effected limb even when the knee joint is flexed or bent. During swing phase, the Neurotronic allows the knee to move freely to achieve a natural gait pattern without the compensations seen with conventional designs.

The electromechanical kneejoint system is controlled either by a pressure sensor under the foot piece or by motion sensors integrated in the controller. The control mechanism incorporates an inclinometer and accelerometer motion sensors that detect the movement and position of the lower leg.

When standing with the orthosis or just before heel strike, the motion sensors lock the Neurotronic system knee joint. The motion detection is sensitive to speed and the joint will lock regardless of length and speed of steps and regardless of a hill gradient.

The SafetyStride is a mechanical stance control orthotic knee joint that utilizes a low-profile cabling system to automatically unlock itself at the end of stance phase. The key feature of the SafetyStride is its ability to resist knee flexion at any angle. The SafetyStride does not require full 180° knee extension to resist knee flexion in stance phase. Designed to unlock at terminal stance, an internal lever re-engages during swing phase to ensure knee joint stability prior to heel contact. Individuals who intermittently fail to reach full extension will now have the added security and stability they require while ambulating. The SafetyStride works in conjunction with the FullStride and can be easily installed on a FullStride equipped KAFO.

If we add a Pneumatic cylinder it will assit the quadriceps muscle and patient feel more comfortable.

The FullStride is a mechanical stance control orthotic knee joint that utilizes a low-profile cabling system to automatically unlock at the end of stance phase. At the end of swing phase, when the orthotic knee joint reaches full extension, the locking mechanism reengages to provide knee stability for stance phase. When necessary, the stance control capability of the FullStride can be easily converted into a traditional automatic bail lock.

If we add a Pneumatic cylinder it will assit the quadriceps muscle and patient feel more comfortable.

A Knee-Ankle-Foot Orthosis (KAFO) is a custom made brace that starts above the knee and extends all the way down the leg to the end of the toes. These braces will normally include a knee joint and possibly an ankle joint as well. A KAFO is prescribed by your physician when there is significant weakness and/or instability at the knee and ankle joints. The KAFO will allow patients to stand by locking the knee joint in the brace when the thigh muscles are too weak to support the knee. This brace can also reduce significant knee hyperextension (genu recurvatum) during the gait cycle. KAFOs can be extended to the hip to provide additional support to the hip joint if necessary.

At your initial assessment you will meet with your Orthotist to go through a complete assessment of your strength and range of motion and undergo an observational gait analysis. There are many different designs of KAFOs, each with different functions and levels of support. In collaboration with your Orthotist at OrthoProActive and your health team, we will determine which KAFO design will help to provide you with the best functional outcomes.

The KAFO is commonly used in the treatment of :

• 1-Blount’s Disease 2-Genu Recurvatum 3-Post-Polio
• 4-Spinal Cord Injury 5-Arthrogryposis 6-Cerebral Palsy
• 7-Polio 8-Spina Bifida
